Accurate analysis of a single-phase dual active bridge converter for ZVS and deadband conditions
Paper in proceeding, 2017
Simplified equations are used for the analysis of a dual active bridge converter leading to a conservative estimation of the zero voltage switching (ZVS) region. The ZVS is directly affected by the inserted deadband in each leg of the converter. In this paper the impact of the ZVS capacitor and deadband on soft switching region for this converter is analyzed. Also, the sufficient constraints for ZVS condition in the input and output bridges are determined by analyzing the circuit behavior during the bridges deadband. Simulation results of a 700V-350V, 50-kW dc-dc converter validate the analysis.
